Abhidhamma Chanting is music to my ears. It reminds me of my time in Chanmyay Yeikthā, Hmawbhi, where the local monastery used to broadcast the chanting over loud-speakers for days on end. I think they used to recite the entire Paṭṭhāna — the chanting at the link is just the introduction.

Isn't it permited for monks to listen to music if they are related to impermanence, for example, reminding of the eminence death? I think I saw that somewhere, but I'm not sure. Of course that the safest way is to not hear it at all, but still, I'm curious.

(Jhana Sutta - Thanissaro Bhikkhu translation)
